Sleeping Disorders List and ICD 9 Diagnostic Codes

There are more than 80 different types of sleep disorders. Sometimes, it's helpful, from a psychological and medical standpoint, to look at the long list of established sleep issues that may affect you.

Diagnosis lists like this exist so that billers can apply the appropriate medical codes for billing and health insurance purposes. But these codes may also help you understand the problem that is disturbing your ability to get a restful night's sleep.

This article offers a comprehensive list of sleeping disorders used by doctors. ICD 9 codes are listed below. Your doctor may use the newer ICD 10 medical codes instead, but the conditions are mostly the same.

Insomnias

Insomnia is defined as difficulty falling or staying asleep or sleep that is not refreshing. Insomnia can affect adults and children. While sometimes there is no identified cause, some common contributors include:

• Poor sleep habits
• Medical conditions
• Psychiatric problems
• Drug use

Insomnia is broken up into many conditions.

Sleep-Related Breathing Disorders

Breathing can be profoundly disrupted during sleep. While unconscious, it becomes difficult to keep the airway open, which may lead to conditions like sleep apnea.

These conditions may result from problems present at birth, the anatomy of the airway, other medical issues, or the use of medications.

Central Sleep Apnea Syndromes

If the brain fails to initiate a breath, a problem called central sleep apnea may occur. Central sleep apnea syndromes include:

Obstructive Sleep Apnea Syndromes

In obstructive sleep apnea, the airway collapses. Pediatric and adult obstructive sleep apnea have the ICD-9 code 327.23. The corresponding ICD-10 code is G47. 33.

Sleep-Related Hypoventilation and Hypoxemic Syndromes

In these sleep disorders, abnormal gas exchange occurs during sleep. Sleep-related hypoventilation and hypoxemic syndromes include:

Hypersomnias of Central Origin

Excessive daytime sleepiness is called hypersomnia. This drowsiness is most often due to a lack of nighttime sleep. However, it may also occur in conditions such as narcolepsy.

Hypersomnia may be related to medication use or other health problems. However, there are also rare conditions that may manifest as excessive sleepiness.

Hypersomnias that are traced to the brain, or those of central origin, include:

Circadian Rhythm Sleep Disorders

The body’s natural pattern of sleep and wakefulness is called the circadian rhythm. When this becomes disrupted or misaligned, it may result in circadian rhythm sleep disorders.

The most common of these types of sleep disorders is jet lag. Another common manifestation is when teenagers are afflicted with a delayed sleep phase. In addition, people who work late or overnight shifts may run into these types of sleep problems.

There are many circadian rhythm sleep disorders.

Parasomnias

Parasomnias are typically abnormal sleep behaviors associated with the two major types of sleep: non-REM and REM sleep. These commonly afflict children, but many persist into adulthood.

There is an association between these types of sleep disorders and particular future diseases, including REM behavior disorder and neurodegenerative diseases such as Parkinson’s disease and Alzheimer’s disease.

These disorders range from bizarre to commonplace and are marked by common things like nightmares or bedwetting. In addition, they are linked to the use of medications or other health problems.

Disorders of Arousal (from Non-REM Sleep)

With these sleep disorders, people do not wake fully, are unresponsive to people trying to wake or interact with them, and have little to no awareness of what is happening during an episode.

Disorders of arousal from non-REM sleep include:

Parasomnias Usually Associated with REM sleep

During REM (rapid eye movement) sleep, a person's eyes move quickly under their eyelids, and their breathing, heart rate, and blood pressure increase. Disorders associated with REM sleep include:

Sleep-Related Movement Disorders

Various conditions result in movements that occur during or before the initiation of sleep. The most common afflictions include teeth grinding, leg cramps, restless legs syndrome, or periodic limb movements.

In totality, the sleep-related movement disorders include:

Other Conditions That Impact Sleep

Beyond the major classes of sleep disorders described above, various other conditions can impact sleep. These may or may not represent a pathological condition, and often they do not. In addition, some conditions are associated with specific medications and psychiatric disorders.

Isolated Symptoms, Apparently Normal Variants, and Unresolved Issues

These conditions fall between what is considered normal and abnormal sleep. They include:

Other Sleep Disorders

These conditions are lumped into the "other" category because they don't neatly fit into other classifications. Other sleep disorders include:

Sleep Disorders Associated with Conditions Classifiable Elsewhere

Sleep disorders associated with conditions classifiable elsewhere include:

Other Psychiatric or Behavioral Disorders Commonly Encountered in the Differential Diagnosis of Sleep Disorders

Psychiatric disorders commonly affect sleep. Other psychiatric or behavioral disorders commonly encountered in the differential diagnosis of sleep disorders include:

• Mood disorders
• Anxiety disorders
• Somatoform disorders
• Schizophrenia and other psychotic disorders
• Disorders usually first diagnosed in infancy, childhood, or adolescence
• Personality disorders

A Word From Verywell

If you believe that you may have a sleep disorder, you should speak with your primary care physician. They may recommend seeing a board-certified sleep specialist to address your concerns.
